The mainland's top law enforcement body has launched a crackdown on people illegally touting train tickets in areas flooded by millions of home-bound migrant workers. A senior Ministry of Public Security official quoted by Xinhuanet.com on Saturday said five taskforces of security officers had been sent to provinces and municipalities, including Beijing, Shanghai, Jiangsu , Fujian and Guangdong province. Tens of millions of migrant workers are employed in factories in Guandong's Pearl River Delta region and along the Yangtze River Delta in Jiangsu and Shanghai. Apart from monitoring the official ticket-selling policy, the taskforces will supervise how local authorities handle cases of ticket scalping, particularly those involving the production and sale of fake tickets. The teams would also crack down on crimes and uphold law and order around railway stations to ensure no hazardous items were taken onto trains, the official said. Checks would be carried out overtly and under cover. Public Security Minister Meng Jianzhu , was in the main railway station in Wuhan , Hubei province , for an on-the-spot security check when the measure was announced on Saturday, the Hubei Daily reported. He pledged to earnestly implement President Hu Jintao's earlier instructions about properly handling transport arrangements for migrant labourers heading home for the Lunar New Year. Mr Meng called on officials to use all efficient means to clamp down on illegal ticket touts. Every year millions of people return home for the holiday, but train tickets can be scarce and it is an open secret that official ticket sellers and illegal ticket scalpers collude.
